Interesting post. I've always struggled with cold hands and feet. Whilst I work hard to protect my hands due to reynauds, I struggle with my feet and have become accustomed to no longer feeling them in the winter running in the fells and particularly on the occasions I go out on the bike.
However, sitting here with frost nip on two toes from an incredibly cold bike ride, I need to start taking the feet far more seriously. Whilst it's only straddling the fence between nip and early frostbite (ie it's red and blistered), I can safely say it's absolute f***ing agony and it's taking ages to heal.
It's definitely something everyone needs to be mindful of, particularly in those situations that don't feel that extreme, (like my bike ride) as the outcome of thinking it'll be alright once you've warmed up could be quite serious.
